The present invention provides a technical field of booster pumping, in particular, a technically provided external ventilating device for a booster pump, wherein the first, second, third and fourth chambers are arranged in the base stepped chamber of the base body. Connect the atmosphere, intake, exhaust, and intake and exhaust respectively, and control the horizontal and vertical perforations provided by the valve stem with all the control stems, so as to achieve automatic cutting, exhaust, and cutting. The control stem sealing shaft is quite flat and easy to process, the machining accuracy is improved, and the overall component is reduced and reduced.

According to the conventional booster pump, the high-pressure gas is mainly used to push a large-area piston, and then the hydraulic oil is pressurized by a small-area piston front-end piston column, thereby converting the high-pressure air pressure into a high-pressure hydraulic pressure. The effect.

However, the conventional booster pump can pressurize the hydraulic pressure by the area ratio, but the gas for each work can not be manually discharged, so the conventional boost pump is to be externally set. An automatic pressure relief device can automatically discharge after the high pressure gas is completed. However, doing so not only causes the equipment to increase, the piping is disordered, and the cost increases. Such problems also make the conventional booster pump more complicated and more problematic. On the other hand, there is also an external external booster pump with a slit control valve stem, but it needs to be provided with more tank chambers, so the parts are more and more complicated, and the conventional cutting and control valve stem needs to be processed more. The groove is difficult to process and the precision is lowered. The convex valve seat area of the conventional cutting and controlling valve stem is small, so that the output pressure is also small, which is missing.
